I think this is because only these stores are the ones that have changelog enabled. Hence, only these stores will restore their changelog into the state store and won't start with an empty store. The rationale then was that the position should match what the state store contains: if the state store is empty, the position should be empty, whereas if the state store is restored from the changelog, the position should be restored from the checkpoint file -- This is an automated message from the Apache Git Service.
